B ending & T ube M anipulation Carbide coating to prevent slippage in bending operations

AN application of Carbinite coating can tighten machinery’s grip on material during bending operations. When applied to the gripper arm in the holding area of mandrel or rotary draw systems the textured coating is said to prevent material from slipping or rolling during bending.

Carbinite is a carbide coating that is electofused to a base metal to add texture. This texture increases the coefficient of friction between the clamping surface and the workpiece allowing for a strong, solid grip in the holding and clamping areas of the tube bending process. Carbinite is applied by electro- fusion, resulting in an incredibly strong bond since the carbide is fused into the base metal, not just applied onto it as in spray welds. Bulk heating is not required, so tool temper and heat treat are not affected. If needed, it can be applied and reapplied without stripping away existing layers. If a metal tube or pipe requires a sequence of bends, an application

in the gripper area of a seeker or plainer will help ensure that when the dye rotates around and the arm comes in contact with the material, slippage does not occur. This prevents the material from being knocked out of plain. The coating is available in several grades, leaving various textures ranging from 40 to 320 emery grit. It can be applied to all steels, including stainless, as well as to certain aluminium alloys such as 6061 and 7075. Carbinite Metal Coatings – USA Fax: +1 724 586 1144
